Suddenly refusing bottles???

Ch

We follow eat play sleep pretty well. She has always done fine with her formula. Suddenly for the past couple weeks, but more in intense recently, she has been pushing away when I offer her a bottle(formula). Or she will only have half then finish it 15-30 minutes later. It’s really starting to concern me because it seems like her milk intake has really dropped. Although, she likes all the purées, oatmeal, yogurt, potatoes, baby wafers. I’m kinda nervous to try table foods because I’m afraid she will choke.

Is this all because she is more interested in actual food now? I thought milk is supposed to be the main nutrition? How do I get her to take a bottle? I don’t know what to do or if this is normal.
